       Ten feet is what the manufacturers suggest (I don't know where this is 
documented). But I've found the above combo have acceptable SWR as close as 
seven feet. This is not true with the XM240 or Force 12 40M antennas. 

      With that much tower, I'd be real tempted to put some antennas stacked 
down the tower too.

     Mast question: What's your county windspeed? (It's on 
www.championradio.com under Tech Notes if you don't know.)
